技术领域Technical field
本公开文本实施例涉及通信应用的技术领域,特别是指一种大尺度信道参数的指示、确定方法、基站及终端。The embodiments of the present disclosure relate to the technical field of communication applications, and in particular, to an indication, a determination method, a base station, and a terminal of a large-scale channel parameter.
背景技术Background technique
鉴于MIMO(Multiple-Input Multiple-Output,多输入多输出)技术对于提高峰值速率与***频谱利用率的重要作用,LTE(Long Term Evolution,长期演进)/LTE-A(LTE-Advanced,增强型长期演进)等无线接入技术标准都是以MIMO+OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)技术为基础构建起来的。MIMO技术的性能增益来自于多天线***所能获得的空间自由度,因此MIMO技术在标准化发展过程中的一个最重要的演进方向便是维度的扩展。In view of the important role of MIMO (Multiple-Input Multiple-Output) technology for improving peak rate and system spectrum utilization, LTE (Long Term Evolution)/LTE-A (LTE-Advanced) Radio access technology standards such as evolution are based on MIMO+OFDM (Orthogonal Frequency Division Multiplexing) technology. The performance gain of MIMO technology comes from the spatial freedom that multi-antenna systems can obtain. Therefore, one of the most important evolution directions of MIMO technology in the development of standardization is the expansion of dimensions.
在LTE Rel-8中,最多可以支持4层的MIMO传输。Rel-9重点对MU-MIMO(Multi-User MIMO,多用户多输入多输出)技术进行了增强,TM(Transmission Mode,传输模式)-8的MU-MIMO传输中最多可以支持4个下行数据层。Rel-10则引入支持8天线端口进一步提高了信道状态信息的空间分辨率,并进一步将SU-MIMO(Single-User MIMO,单用户多输入多输出)的传输能力扩展至最多8个数据层。Rel-13和Rel-14引入了FD-MIMO技术支持到32端口,实现全维度以及垂直方向的波束赋形。In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Rel-9 focuses on MU-MIMO (Multi-User MIMO, Multi-User Multiple Input Multiple Output) technology, and supports up to 4 downlink data layers in MU-MIMO transmission of TM (Transmission Mode)-8 . Rel-10 introduces support for 8 antenna ports to further improve the spatial resolution of channel state information, and further expands the transmission capability of SU-MIMO (Single-User MIMO, single-user multiple input multiple output) to a maximum of 8 data layers. Rel-13 and Rel-14 introduce FD-MIMO technology to support 32 ports for beamforming in both full and vertical directions.
为了进一步提升MIMO技术,移动通信***中引入大规模天线技术。对于基站,全数字化的大规模天线可以有高达128/256/512个天线振子,以及高达128/256/512个收发信机,每个天线振子连接一个收发信机。通过发送高达128/256/512个天线端口的导频信号,使得终端测量信道状态信息并反馈。对 于终端,也可以配置高达32/64个天线振子的天线阵列。通过基站和终端两侧的波束赋形,获得巨大的波束赋形增益,以弥补路径损耗带来的信号衰减。尤其是在高频段通信,例如30GHz频点上,路径损耗使得无线信号的覆盖范围极其有限。通过大规模天线技术,可以将无线信号的覆盖范围扩大到可以实用的范围内。In order to further enhance MIMO technology, large-scale antenna technology is introduced in mobile communication systems. For base stations, fully digital large-scale antennas can have up to 128/256/512 antenna elements and up to 128/256/512 transceivers, each connected to a transceiver. The terminal measures channel state information and feeds back by transmitting pilot signals up to 128/256/512 antenna ports. For the terminal, an antenna array of up to 32/64 antenna elements can also be configured. Through the beamforming on both sides of the base station and the terminal, a huge beamforming gain is obtained to compensate for the signal attenuation caused by the path loss. Especially in high-band communications, such as the 30 GHz frequency, the path loss makes the coverage of wireless signals extremely limited. With large-scale antenna technology, the coverage of wireless signals can be expanded to a practical range.
全数字天线阵列,每个天线振子都有独立的收发信机,将会使得设备的尺寸、成本和功耗大幅度上升。特别是对于收发信机的模数转换器(ADC)和数模转换器(DAC),功耗降低和性能提升都比较有限。为了降低设备的尺寸、成本和功耗,基于模拟波束赋形的技术方案被提出。为了进一步提升模拟波束赋形性能,数字模拟混合波束赋形收发架构方案被提出,混合波束赋形结构在数字波束赋形灵活性和模拟波束赋形的低复杂度间做了平衡。All-digital antenna arrays, each with an independent transceiver, will greatly increase the size, cost and power consumption of the device. Especially for transceiver analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), power reduction and performance improvement are limited. In order to reduce the size, cost and power consumption of the device, a technical solution based on analog beamforming has been proposed. In order to further improve the analog beamforming performance, a digital analog hybrid beamforming transceiver architecture scheme has been proposed, and the hybrid beamforming structure balances the digital beamforming flexibility with the low complexity of analog beamforming.
模拟波束赋形和数模混合波束赋形都需要调整收发两端的模拟波束赋形权值,以使得其所形成的波束能对准通信的对端。但现有技术中,在数据传输之前,接收端难以确定与下行接收相关的大尺度信道参数,如空间参数,进而不能设置合理的接收波束,降低了终端的接收可靠性。Both analog beamforming and digital-to-analog hybrid beamforming require adjustment of the analog beamforming weights at both ends of the transceiver so that the resulting beam can be aligned with the opposite end of the communication. However, in the prior art, before the data transmission, the receiving end has difficulty determining the large-scale channel parameters related to the downlink reception, such as the spatial parameters, and thus cannot set a reasonable receiving beam, thereby reducing the receiving reliability of the terminal.

步骤101:确定与传输信道针对一个或一组大尺度信道参数相关的第一传输资源,并将所述第一传输资源的配置信息,通过第一信令发送给终端,所述第一传输资源为K个下行参考信号的传输资源,K为正整数。Step 101: Determine a first transmission resource related to one or a group of large-scale channel parameters, and send the configuration information of the first transmission resource to the terminal by using the first signaling, where the first transmission resource For the transmission resources of the K downlink reference signals, K is a positive integer.

The second transmission resource is a transmission resource of L downlink reference signals, where L is a positive integer, and K is greater than or equal to L.
这里的指示信息可具体包括所述第二传输资源在所述第一传输资源中的编号信息。上述第二信令可具体为下行控制信息DCI。上述传输参数可具体为发送波束或发送的传输点。The indication information herein may specifically include the number information of the second transmission resource in the first transmission resource. The foregoing second signaling may be specifically downlink control information DCI. The above transmission parameters may be specifically a transmission beam or a transmission point.
该步骤中将指示信息发送给终端,使得终端根据所述指示信息及所述K 个下行参考信号的大尺度信道参数,获取K个下行参考信号中的L个下行参考信号的大尺度信道参数。In this step, the indication information is sent to the terminal, so that the terminal acquires the large-scale channel parameters of the L downlink reference signals in the K downlink reference signals according to the indication information and the large-scale channel parameters of the K downlink reference signals.
本公开文本实施例的大尺度信道参数的指示方法,基站确定与传输信道针对一个或一组大尺度信道参数相关的第一传输资源,并将所述第一传输资源的配置信息,通过第一信令发送给终端,所述第一传输资源为K个下行参考信号的传输资源;根据传输信道所使用的传输参数,在所述第一传输资源中选取第二传输资源,并将第二传输资源的指示信息,通过第二信令发送给所述终端,所述第二传输资源为L个下行参考信号的传输资源,使所述终端根据所述指示信息及所述第一传输资源的配置信息,确定所述传输信道的大尺度参数,进而使得终端能够根据该传输信道的大尺度参数,确定相应的接收波束,提高了终端的接收可靠性。In the method for indicating a large-scale channel parameter of the embodiment of the present disclosure, the base station determines a first transmission resource related to one or a group of large-scale channel parameters of the transmission channel, and passes the configuration information of the first transmission resource to the first The signaling is sent to the terminal, where the first transmission resource is a transmission resource of K downlink reference signals; according to a transmission parameter used by the transmission channel, a second transmission resource is selected in the first transmission resource, and the second transmission is performed. The indication information of the resource is sent to the terminal by using the second signaling, where the second transmission resource is a transmission resource of the L downlink reference signals, and the terminal is configured according to the indication information and the first transmission resource. The information is used to determine a large-scale parameter of the transmission channel, so that the terminal can determine a corresponding receiving beam according to the large-scale parameter of the transmission channel, and improve the receiving reliability of the terminal.
第二实施例Second embodiment
如图2所示,本公开文本实施例的大尺度信道参数的指示方法,应用于基站,包括:As shown in FIG. 2, the method for indicating a large-scale channel parameter in the embodiment of the present disclosure is applied to a base station, including:
步骤201:为所述终端配置第三传输资源,并通过第三信令将所述第三传输资源的配置信息发送给所述终端,所述第三传输资源为N个下行参考信号的传输资源,且N大于或者等于K。Step 201: Configure a third transmission resource for the terminal, and send configuration information of the third transmission resource to the terminal by using a third signaling, where the third transmission resource is a transmission resource of N downlink reference signals. And N is greater than or equal to K.
具体的,基站通过信令为终端配置N个下行参考信号的传输资源,该下行参考信号可具体为信道状态信息参考信号CSI-RS。每个下行参考信号的传输资源的配置信息包括一组下行参考信号端口传输的时频资源,下行参考信号的序列配置信息等。这里的信令为高层信令或者广播消息。Specifically, the base station configures, by using the signaling, a transmission resource of the N downlink reference signals, where the downlink reference signal may be specifically a channel state information reference signal CSI-RS. The configuration information of the transmission resource of each downlink reference signal includes a time-frequency resource of a downlink reference signal port transmission, sequence configuration information of a downlink reference signal, and the like. The signaling here is high layer signaling or broadcast message.
假定上述下行参考信号为CSI-RS,则上述N个CSI-RS资源可以包括用于波束管理过程的所有的CSI-RS传输资源,且上述CSI-RS传输资源替换成CSI-RS端口组,或者CSI-RS端口,后续方法同样适用。Assuming that the downlink reference signal is a CSI-RS, the foregoing N CSI-RS resources may include all CSI-RS transmission resources used in the beam management process, and the CSI-RS transmission resources are replaced with CSI-RS port groups, or The CSI-RS port, the same method applies.
进一步地,每个CSI-RS传输资源包括P个CSI-RS端口。例如,P=1,2,或者其他值。P的取值可以是基站通过信令配置的,即基站为每个CSI-RS传输资源设置P的取值,并将其取值在CSI-RS传输资源的配置信息中发送给终端。P的取值也可以是固定值,例如在协议中约定P=1。Further, each CSI-RS transmission resource includes P CSI-RS ports. For example, P=1, 2, or other value. The value of the P may be configured by the base station by using the signaling, that is, the base station sets the value of the P for each CSI-RS transmission resource, and sends the value to the terminal in the configuration information of the CSI-RS transmission resource. The value of P can also be a fixed value, for example, P=1 is agreed in the protocol.
每个CSI-RS传输资源通过一个发送波束发出,不同的CSI-RS资源对应 的发送波束可以不同。Each CSI-RS transmission resource is sent through one transmission beam, and the transmission beams corresponding to different CSI-RS resources may be different.
该步骤通过配置N个下行参考信号的传输资源,该N各下行参考信号资源为波束管理过程中的所有下行参考信号资源,使得终端能够更加全面地获取传输信道的大尺度信道参数。In this step, the transmission resources of the N downlink reference signals are configured, and the N downlink reference signal resources are all downlink reference signal resources in the beam management process, so that the terminal can acquire the large-scale channel parameters of the transmission channel more comprehensively.
步骤202:在所述第三传输资源中,确定第一传输资源,并将所述第一传输资源的配置信息,通过第一信令发送给终端,所述第一传输资源为K个下行参考信号的传输资源,K为正整数。Step 202: Determine, in the third transmission resource, the first transmission resource, and send the configuration information of the first transmission resource to the terminal by using the first signaling, where the first transmission resource is K downlink reference The transmission resource of the signal, K is a positive integer.
具体的可通过以下实现方式来实现:The specific implementation can be achieved by the following implementations:
获取所述终端或基站本身按照预设质量指标,对所述第三传输资源进行测量的测量结果;根据所述测量结果,在所述第三传输资源中,确定所述第一传输资源。Obtaining a measurement result that the terminal or the base station itself performs measurement on the third transmission resource according to a preset quality indicator; and determining, according to the measurement result, the first transmission resource in the third transmission resource.
进一步地,可对所述第三传输资源的测量结果按照由高到低的顺序进行排序,得到一排序列表;确定所述排序列表中的前K个测量结果对应的下行参考信号的传输资源为所述第一传输资源。Further, the measurement result of the third transmission resource may be sorted in descending order to obtain a sorted list; and the transmission resource of the downlink reference signal corresponding to the first K measurement results in the sorted list is determined to be The first transmission resource.
或者,根据所述测量结果,确定最佳下行参考信号的传输资源所使用的第一发送波束;确定与所述第一发送波束相邻的K个第二发送波束,所述第二发送波束与所述第一发送波束的空间指向角度之差在预设范围内;确定与所述K个第二发送波束对应的K个下行参考信号的传输资源为所述第一传输资源。Or determining, according to the measurement result, a first transmit beam used by a transmission resource of an optimal downlink reference signal; determining K second transmit beams adjacent to the first transmit beam, where the second transmit beam is The difference between the spatial directivity angles of the first transmit beams is within a preset range; and the transmission resources of the K downlink reference signals corresponding to the K second transmit beams are determined to be the first transmission resources.
基站从第三传输资源中,激活K个下行参考信号的传输资源,用于进行大尺度信道参数跟踪。该实现方式中,假定上述下行参考信号为CSI-RS,大尺度信道参数为空间参数,基站基于终端的测量上报或者基站自行进行的测量确定需要激活的CSI-RS传输资源。其中,若某个CSI-RS传输资源被激活,则该CSI-RS传输资源属于第一传输资源,所有激活的CSI-RS传输资源构成第一传输资源。例如,基站为终端配置N个CSI-RS传输资源,每个CSI-RS传输资源所传输的CSI-RS通过一个波束发送。终端测量N个CSI-RS传输资源并选择质量最佳的Q个CSI-RS传输资源,将Q个CSI-RS传输资源的标识以及其质量指标反馈给基站。质量指标可以是参考信号接收功率(RSRP),或者信道状态信息(CSI)等。基站接收终端反馈的信息,据此确定需要激活 的CSI-RS传输资源。例如,激活终端上报的Q个CSI-RS资源,此时K=Q。或者激活质量最佳的一个CSI-RS传输资源的波束周围相邻的K个波束所传输的CSI-RS资源,此时K由基站根据***开销要求和终端的能力确定,且相邻波束是指波束的空间指向角度相邻。空间指向角度相邻是指两者的空间指向角度之差在预设范围内。The base station activates transmission resources of the K downlink reference signals from the third transmission resource for performing large-scale channel parameter tracking. In this implementation manner, it is assumed that the downlink reference signal is a CSI-RS, and the large-scale channel parameter is a spatial parameter, and the base station determines, according to the measurement report of the terminal or the measurement performed by the base station, the CSI-RS transmission resource that needs to be activated. Wherein, if a certain CSI-RS transmission resource is activated, the CSI-RS transmission resource belongs to the first transmission resource, and all activated CSI-RS transmission resources constitute the first transmission resource. For example, the base station configures N CSI-RS transmission resources for the terminal, and the CSI-RS transmitted by each CSI-RS transmission resource is transmitted through one beam. The terminal measures N CSI-RS transmission resources and selects the Q CSI-RS transmission resources with the best quality, and feeds back the identifiers of the Q CSI-RS transmission resources and the quality indicators thereof to the base station. The quality indicator may be Reference Signal Received Power (RSRP), or Channel State Information (CSI), and the like. The base station receives the information fed back by the terminal, and determines the CSI-RS transmission resource that needs to be activated accordingly. For example, the Q CSI-RS resources reported by the terminal are activated, and K=Q at this time. Or activating CSI-RS resources transmitted by neighboring K beams around a beam of the best quality CSI-RS transmission resource, where K is determined by the base station according to system overhead requirements and capabilities of the terminal, and the adjacent beam refers to The spatial orientation of the beams is adjacent to the angle. The spatial pointing angle adjacent means that the difference between the spatial pointing angles of the two is within a preset range.
另外,上述实现方式中,基站通过MAC CE控制单元激活(Activate)N个CSI-RS资源中的K个CSI-RS传输资源,K小于或者等于N。激活的信令生效后,终端开始根据激活的K个CSI-RS传输资源进行空间参数的跟踪,并维持对K个CSI-RS传输资源的空间参数跟踪,保存相应的空间参数。In addition, in the foregoing implementation manner, the base station activates K CSI-RS transmission resources in the N CSI-RS resources by using a MAC CE control unit, where K is less than or equal to N. After the active signaling takes effect, the terminal starts tracking the spatial parameters according to the activated K CSI-RS transmission resources, and maintains the spatial parameter tracking of the K CSI-RS transmission resources, and saves the corresponding spatial parameters.
K个CSI-RS传输资源是周期性的或者半持续性的。对于半持续性的CSI-RS资源,其CSI-RS的传输可以与激活的信令进行绑定,即CSI-RS在激活之后开始进行传输,去激活之后停止传输。对于半持续性的CSI-RS资源,其CSI-RS的传输也可以独立于激活的信令,即CSI-RS的传输启动与停止通过其他独立的信令进行控制。The K CSI-RS transmission resources are periodic or semi-persistent. For semi-persistent CSI-RS resources, the transmission of CSI-RS can be bound to the activated signaling, that is, the CSI-RS starts transmission after activation, and stops after deactivation. For a semi-persistent CSI-RS resource, the transmission of the CSI-RS may also be independent of the activated signaling, that is, the transmission start and stop of the CSI-RS are controlled by other independent signaling.
激活和去激活(Deactivate)可以采用增量的方式。即假设当前有M1个激活的CSI-RS资源,基站又通过MAC CE激活了M2个资源,则在激活信令生效后激活的CSI-RS资源将包括当前的M1个激活的CSI-RS资源以及新增的M2个CSI-RS资源,共计有M1+M2个(假设两者没有重复)。假设当前有M1个激活的CSI-RS资源,如果基站通过MAC去激活了其中的M3个CSI-RS资源,则在去激活信令生效后的激活的CSI-RS资源,将包括则当前激活的CSI-RS资源除去已经去激活的M3个CSI-RS资源,共计有M1-M3个。Activation and deactivation can be done incrementally. That is, if there are currently M1 active CSI-RS resources, and the base station activates M2 resources through the MAC CE, the CSI-RS resources activated after the activation signaling takes effect will include the current M1 activated CSI-RS resources and The newly added M2 CSI-RS resources have a total of M1+M2 (assuming there is no duplication between the two). Suppose that there are currently M1 active CSI-RS resources. If the base station deactivates the M3 CSI-RS resources through the MAC, the activated CSI-RS resources after the deactivation signaling takes effect will include the currently activated The CSI-RS resource removes M3 CSI-RS resources that have been deactivated, and there are a total of M1-M3.
激活和去激活也可以采用绝对量的方式。即在一个激活信令生效后,激活的CSI-RS传输资源将只包括生效的激活信令中指示的CSI-RS传输资源,当前激活的CSI-RS传输资源若不在当前生效的激活信令指示的范围内,则自动进行去激活。Activation and deactivation can also be done in absolute quantities. That is, after an activation signaling takes effect, the activated CSI-RS transmission resource will only include the CSI-RS transmission resource indicated in the active activation signaling, and the currently activated CSI-RS transmission resource is not in the currently active activation signaling indication. Within the scope, it is automatically deactivated.
关于CSI-RS传输资源的传输:Regarding the transmission of CSI-RS transmission resources:
A)一个CSI-RS传输资源激活后的传输方式和激活前的传输方式不同,例如周期不同,激活之后采用更小的周期传输;例如子载波间隔不同,激活 之后采用更大的子载波间隔传输;例如在一个周期内传输的次数不同,激活之后在一个周期内进行更多次的传输;A) The transmission mode after activation of a CSI-RS transmission resource is different from the transmission mode before activation, for example, the period is different, and the transmission is performed after a smaller period after activation; for example, the subcarrier spacing is different, and the transmission is performed after a larger subcarrier interval after activation. For example, the number of transmissions is different in one cycle, and more transmissions are performed in one cycle after activation;
B)一个CSI-RS资源激活后的传输方式和激活前相同。B) The transmission mode after a CSI-RS resource is activated is the same as before the activation.
步骤203:在所述第一传输资源中,选取与所述传输信道的传输参数相同或相关的传输资源作为所述第二传输资源,并将所述第二传输资源的指示信息,通过第二信令发送给所述终端,所述第二传输资源为L个下行参考信号的传输资源,L为正整数,且K大于或者等于L。Step 203: In the first transmission resource, select a transmission resource that is the same as or related to a transmission parameter of the transport channel as the second transmission resource, and pass the indication information of the second transmission resource to the second The signaling is sent to the terminal, where the second transmission resource is a transmission resource of L downlink reference signals, L is a positive integer, and K is greater than or equal to L.
具体的,在所述第一传输资源中,选取与所述传输信道的传输参数相同或相关的传输资源作为所述第二传输资源。Specifically, in the first transmission resource, a transmission resource that is the same as or related to a transmission parameter of the transport channel is selected as the second transmission resource.
进一步地,在所述第一传输资源中,选取与所述传输信道的传输参数相同传输资源作为所述第二传输资源的步骤,包括:Further, in the first transmission resource, the step of selecting the same transmission resource as the transmission parameter of the transmission channel as the second transmission resource includes:
在所述的第一传输资源中,选取与所述传输信道的使用相同发送波束的传输资源作为所述第二传输资源。In the first transmission resource, a transmission resource that uses the same transmission beam as the transmission channel is selected as the second transmission resource.
进一步地,在所述第一传输资源中,选取与所述传输信道的传输参数相关的传输资源作为所述第二传输资源的步骤,包括:Further, in the first transmission resource, the step of selecting a transmission resource related to the transmission parameter of the transmission channel as the second transmission resource includes:
确定与所述传输信道使用的发送波束处于同一波束组的相关发送波束,并在所述第一传输资源中,选取使用所述相关发送波束发送的传输资源作为所述第二传输资源。其中,空间指向角处于预设范围内或同一波束组中的多个发送波束为同一波束组或使用同一接收波束进行接收的多个发送波束为同一波束组。Determining an associated transmit beam that is in the same beam group as the transmit beam used by the transport channel, and selecting, in the first transmit resource, a transmission resource that is sent by using the associated transmit beam as the second transmit resource. The plurality of transmit beams whose spatial directivity angles are within a preset range or in the same beam group are the same beam group or are received by using the same receive beam are the same beam group.
上述步骤203中,基站从K个用于进行大尺度信道参数(空间参数)跟踪下行参考信号的传输资源,如CSI-RS传输资源中,选择L个CSI-RS传输资源,并将L个CSI-RS传输资源的指示信息通过DCI发送给终端。In the foregoing step 203, the base station selects L CSI-RS transmission resources, and sets L CSIs from K transmission resources for performing large-scale channel parameters (spatial parameters) tracking downlink reference signals, such as CSI-RS transmission resources. The indication information of the RS transmission resource is transmitted to the terminal through the DCI.
终端接收基站发送的DCI,确定L个CSI-RS传输资源。终端根据这L个CSI-RS传输资源上获得的空间参数确定数据信道或者控制信道的空间参数,从而确定数据信道或者控制信道的接收波束。The terminal receives the DCI sent by the base station, and determines L CSI-RS transmission resources. The terminal determines a spatial parameter of the data channel or the control channel according to the spatial parameter obtained on the L CSI-RS transmission resources, thereby determining a receive beam of the data channel or the control channel.
基站在DCI信令生效后使用上述数据或者控制信道的发送波束向终端发送数据或者控制信号。终端则在DCI信令生效后用确定的接收波束接收数据或者控制信号。如果DCI信令在子帧(或者时隙)n传输,DCI信令的生效 时间是n+l,即DCI信令指示的信息在子帧(时隙)n+l生效,如果l=0,则DCI信令在传输DCI的子帧(时隙)内即生效。l的取值可以在协议中约定为固定值,或者在DCI中进行指示。After the DCI signaling is valid, the base station uses the above data or the transmit beam of the control channel to send data or control signals to the terminal. The terminal receives data or control signals with the determined receive beam after the DCI signaling takes effect. If the DCI signaling is transmitted in a subframe (or a time slot) n, the effective time of the DCI signaling is n+1, that is, the information indicated by the DCI signaling is valid in the subframe (time slot) n+1, if l=0, Then the DCI signaling takes effect within the subframe (time slot) in which the DCI is transmitted. The value of l can be agreed to as a fixed value in the protocol or indicated in the DCI.
下面结合具体例子来说明上述步骤203的实现过程。The implementation process of the above step 203 will be described below with reference to specific examples.
例一Example 1
假设基站确定向终端发送数据或者控制信道所使用的发送波束是波束A和波束B,则基站应从用于进行空间参数跟踪的K个CSI-RS资源中选择同样使用波束A和波束B发送的CSI-RS资源(记为CSI-RS资源A和CSI-RS资源B),并将CSI-RS资源A和CSI-RS资源B在用于进行空间参数跟踪的K个CSI-RS资源中的编号,通过DCI通知给终端。Assuming that the base station determines to transmit data to the terminal or the transmit beam used by the control channel is beam A and beam B, the base station should select the CSI that is also transmitted using beam A and beam B from among the K CSI-RS resources used for spatial parameter tracking. -RS resources (denoted as CSI-RS resource A and CSI-RS resource B), and numbers of CSI-RS resource A and CSI-RS resource B in K CSI-RS resources used for spatial parameter tracking, Notify the terminal through DCI.
例二Case 2
假设基站确定向终端发送数据或者控制信道所使用的发送波束是波束A,则基站应从用于进行空间参数跟踪的K个CSI-RS资源中选择同样使用波束A发送的CSI-RS资源(记为CSI-RS资源A),并将CSI-RS资源A在用于进行空间参数跟踪的K个CSI-RS资源中的编号,通过DCI通知给终端。Assuming that the base station determines to transmit data to the terminal or the transmit beam used by the control channel is beam A, the base station should select the CSI-RS resource that is also transmitted using the beam A from among the K CSI-RS resources used for spatial parameter tracking (denoted as The CSI-RS resource A), and the number of the CSI-RS resource A in the K CSI-RS resources used for performing spatial parameter tracking is notified to the terminal through the DCI.
例三Example three
假设基站确定向终端发送数据或者控制信道所使用的发送波束是波束A,则基站应从用于进行空间参数跟踪的K个CSI-RS资源中选择波束B发送的CSI-RS资源(记为CSI-RS资源B),且波束B与波束A属于同一个波束组,并将CSI-RS资源B在用于进行空间参数跟踪的K个CSI-RS资源中的编号,通过DCI通知给终端。波束组是基站根据波束的空间指向进行划分,例如将空间指向在一定范围内的波束划分为一个波束组;或者根据终端的反馈信息进行划分,例如终端根据测量确定可以使用同一个接收波束进行接收的波束划分一个波束组,并将波束分组的信息反馈给基站。Assuming that the base station determines to transmit data to the terminal or the transmission beam used by the control channel is beam A, the base station should select the CSI-RS resource transmitted by the beam B from the K CSI-RS resources used for spatial parameter tracking (referred to as CSI- RS resource B), and beam B and beam A belong to the same beam group, and the number of CSI-RS resource B in the K CSI-RS resources used for spatial parameter tracking is notified to the terminal through DCI. The beam group is divided by the base station according to the spatial direction of the beam. For example, the beam that points the space to a certain range is divided into one beam group, or is divided according to the feedback information of the terminal. For example, the terminal determines that the same receiving beam can be used for receiving according to the measurement. The beam splits a beam group and feeds back the information of the beam packet to the base station.
上述用接收波束A接收数据或者控制信号是指采用接收波束A对应的波束赋形权值对多个天线振子上接收到的信号进行加权合并,得到一路信号输出再进行后续的处理过程。The receiving of the data or the control signal by the receiving beam A refers to weighting and combining the signals received on the plurality of antenna elements by using the beam shaping weight corresponding to the receiving beam A, and obtaining a signal output for subsequent processing.
同理,用发送波束B发送数据或者控制信号是指采用发送波束B对应的波束赋形权值对一路输入信号(控制或者数据信道的信号)进行加权之后从 多个天线振子上发送出去。Similarly, transmitting data or control signals by using the transmit beam B means that the input signal (the signal of the control or data channel) is weighted by the beam shaping weight corresponding to the transmit beam B and then transmitted from the plurality of antenna elements.
本公开文本实施例的大尺度信道参数的指示方法,基站通过MAC CE和DCI两级指示信息来指示传输信道的大尺度信道参数,使得终端能够根据两级指示信息来获取传输信道的大尺度信道参数,进而确定传输信道的下行接收波束,且通过两级指示信息来指示传输信道的大尺度信道参数,在性能和复杂度之间达到比较好的折中(tradeoff)。In the method for indicating a large-scale channel parameter of the embodiment of the present disclosure, the base station indicates the large-scale channel parameter of the transmission channel by using the two-level indication information of the MAC CE and the DCI, so that the terminal can acquire the large-scale channel of the transmission channel according to the two-level indication information. The parameters, in turn, determine the downlink receive beam of the transport channel, and indicate the large-scale channel parameters of the transport channel through two levels of indication information, achieving a good tradeoff between performance and complexity.
第三实施例Third embodiment
如图3所示,本公开文本实施例的大尺度信道参数的指示方法,应用于基站,包括:As shown in FIG. 3, the method for indicating a large-scale channel parameter in the embodiment of the present disclosure is applied to a base station, including:
步骤301:为所述终端配置第三传输资源,并通过第三信令将所述第三传输资源发送给所述终端,所述第三传输资源为N个下行参考信号的传输资源,且N大于或者等于K。Step 301: Configure a third transmission resource for the terminal, and send the third transmission resource to the terminal by using a third signaling, where the third transmission resource is a transmission resource of N downlink reference signals, and Greater than or equal to K.
该步骤与上述步骤201相同,此处不再赘述。This step is the same as step 201 above, and details are not described herein again.
步骤302:根据第三传输资源,对下行参考信号的传输资源进行配置处理,得到第一传输资源及第一传输资源的配置信息,并将第一传输资源的配置信息,通过第一信令发送给终端,配置信息包括大尺度信道参数指示信息,大尺度信道参数指示信息用于指示第一传输资源中的每个传输资源的天线端口,与第三传输资源中的一个或多个传输资源的天线端口,针对一个或者一组大尺度信道参数的相关信息。Step 302: Perform configuration processing on the transmission resource of the downlink reference signal according to the third transmission resource, obtain configuration information of the first transmission resource and the first transmission resource, and send configuration information of the first transmission resource by using the first signaling. For the terminal, the configuration information includes large-scale channel parameter indication information, and the large-scale channel parameter indication information is used to indicate an antenna port of each transmission resource in the first transmission resource, and one or more transmission resources in the third transmission resource Antenna port, for information about one or a set of large-scale channel parameters.
该相关信息可具体为准共站址QCL信息。The related information may specifically be quasi-co-site QCL information.
基站确定K个下行参考信号的传输资源,用于进行大尺度信道参数跟踪。The base station determines transmission resources of the K downlink reference signals for performing large-scale channel parameter tracking.
假定上述下行参考信号为CSI-RS,大尺度信道参数为空间参数,基站在MAC CE中对K个CSI-RS传输资源的参数进行配置,包括对CSI-RS的资源的时频资源位置,周期,CSI-RS信号的序列,端口数等。此时这K个CSI-RS资源可以和上述步骤301中的N个CSI-RS资源之间独立。进一步的,K个CSI-RS传输资源的配置信息中包括空间参数指示信息,即每个CSI-RS传输资源的天线端口与N个CSI-RS资源中的天线端口关于一个或者多个空间参数是准共站址QCL的。It is assumed that the downlink reference signal is a CSI-RS, and the large-scale channel parameter is a spatial parameter. The base station configures parameters of the K CSI-RS transmission resources in the MAC CE, including the time-frequency resource location of the CSI-RS resource, and the period. , the sequence of the CSI-RS signal, the number of ports, and the like. At this time, the K CSI-RS resources may be independent of the N CSI-RS resources in the foregoing step 301. Further, the configuration information of the K CSI-RS transmission resources includes spatial parameter indication information, that is, the antenna port of each CSI-RS transmission resource and the antenna port of the N CSI-RS resources are related to one or more spatial parameters. Quasi-common site QCL.
MAC CE信令生效后,终端开始根据K个CSI-RS传输资源进行空间参 数的跟踪,并维持对K个CSI-RS传输资源的空间参数跟踪,保存相应的空间参数。After the MAC CE signaling takes effect, the terminal starts tracking the spatial parameters according to the K CSI-RS transmission resources, and maintains the spatial parameter tracking of the K CSI-RS transmission resources, and saves the corresponding spatial parameters.
K个CSI-RS资源是周期性的或者半持续性的。对于半持续性的CSI-RS传输资源,其CSI-RS的传输可以与MAC CE信令进行绑定,即CSI-RS在MAC CE信令生效之后开始进行传输,失效之后停止传输。对于半持续性的CSI-RS传输资源,其CSI-RS的传输也可以独立于MAC CE,即CSI-RS的传输启动与停止通过其他独立的信令进行控制。The K CSI-RS resources are periodic or semi-persistent. For a semi-persistent CSI-RS transmission resource, the transmission of the CSI-RS may be bound to the MAC CE signaling, that is, the CSI-RS starts to transmit after the MAC CE signaling takes effect, and stops after the failure. For a semi-persistent CSI-RS transmission resource, the transmission of the CSI-RS may also be independent of the MAC CE, that is, the transmission start and stop of the CSI-RS are controlled by other independent signaling.
作为一个示例,若上述配置信息包括所述第一传输资源按照预设分组标准进行分组后的分组信息,所述预设分组标准包括:将大尺度信道参数相同的下行参考信号的传输资源划分为一组,或者将使用同一个接收波束进行接收的传输资源划分为一组,或将具有相同信道传输要求的传输资源划分为一组。As an example, if the configuration information includes the grouping information after the first transmission resource is grouped according to a preset grouping criterion, the preset grouping criterion includes: dividing the transmission resource of the downlink reference signal with the same large-scale channel parameter into A group, or a transmission resource that uses the same receive beam for reception into a group, or a transmission resource having the same channel transmission requirement is divided into one group.
此时,终端在进行大尺度信道参数跟踪时,可以基于上述配置信息对具有相同分组信息的传输资源进行联合跟踪,从而能够更加迅速地确定第一传输资源所传输的K个下行参考信号的大尺度信道参数。At this time, when performing the large-scale channel parameter tracking, the terminal may perform joint tracking on the transmission resources having the same grouping information based on the foregoing configuration information, so that the K downlink reference signals transmitted by the first transmission resource can be determined more quickly. Scale channel parameters.
下面以下行参考信号为CSI-RS为例进行说明。The following line reference signal is used as an example for the CSI-RS.
对CSI-RS传输资源进行分组,空间参数相同的CSI-RS资源分为一组,例如分为F组。基站在配置信息中将分组信息发送给终端。The CSI-RS transmission resources are grouped, and the CSI-RS resources with the same spatial parameters are grouped into one group, for example, divided into F groups.
